#11106: Turning on optimizer changes behavior in 7.10.3 -------------------------------------+------------------------------------- Reporter: dsf | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): The test case is now narrowed down a lot, 60 lines in total. The problem seems to be related to polymorphic, exported definitions: If I start to remove type signatures or to merge some of the module, it disappears. This needs looking into by someone with knowledge about the constraint solver. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11106#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
